Especially not Jonah Hill, who all but declared war on Matthew Morrison, the actor who plays Glee’s oft-maligned teacher/occasional rapper, during his visit to Late Night with Jimmy Fallon on Wednesday. The newly-svelte Moneyball star recalled a recent incident in which he attended a “douchey Hollywood party” where he tried to eavesdrop on a conversation between “Gossip Girl guy” Chace Crawford and Morrison, who had previously ridiculed him at a Fox television event (here’s that part of the story), only to hear that the Glee actor made a joke in which “Jonah Hill” was the uproarious punchline. It is on, PopWatchers.

Not only did Hill call Morrison out on national television with some flowery Sitter-like language (“Yo, Matthew Morrison, you better bring your s— next time I see you”), but he also earned some major street cred from the Roots (Questlove gave him a standing-O!). Check out the full clip below in which Hill draws the battle lines of this latest celebrity feud (“I’d like to see him sing his way out of this one!”).
